There is 1 Strength Based Skill"And the fighter has the 2nd worst rolls outside of combat."
I am sorry, but how is this even a statement. The second worst at what? Athletics? Acrobatics? And what about the third 14? That accounts for something, somewhere? How about this, if you want to be a fighter who rocks at skills, convince the DM to use feats and take Skilled. Better yet, if you are using point buy, take the three 13s and 3 12s. Combine it with Skilled, use Tasha's Tool option, and you have quite the skilled fighter.
There are 3 Dexterity Based Skills
There are 0 Constitution Based Skills
There are 5 Intelligence Based Skills
There are 5 Wisdom Based Skills
There are 4 Charisma Based Skills
Social Interaction Primarily uses Wisdom and Charisma Checks
Exploration Primary uses Strength, Dexterity, Intelligence, and Wisdom Checks
A Fighter's Primary and Secondary Scores are Strength and Dexterity. So a fighter's base ability focus matches up with 4/13 Exploration Skills and 0/5 Social Skills.
Every other class except the barbarian can do better the 4/13 and 0/5 AND/OR has a base class feature to increase that number (Such as Expertise, Favored Enemy, or Jack of All Trades).
The fighter has the 2nd worst rolls outside of combat.
